Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631350, here are decompositions:

19 + 8631331 = 8631350
31 + 8631319 = 8631350
43 + 8631307 = 8631350
67 + 8631283 = 8631350
73 + 8631277 = 8631350
103 + 8631247 = 8631350
151 + 8631199 = 8631350
157 + 8631193 = 8631350

Showing the first eight; more decompositions exist.
